Peterals 400 Grams - Natural Mineral Rocks to Prevent Lawn Grass Burn Yellow Patches from Dog Urine

Works perfectly. I use a 5 gallon container and I keep it in the refrigerator. I refilled it every night . Dogs had no issues with the taste or any other people's. I am very happy that my lawn come back in less than 2 weeks

I have 2 corgis with short legs that hate walking in the wet grass in the morning, so they rarely walk past the edge of the sidewalk to do their business. These rocks 100% fixed my brown grass problem over the course of six weeks. You must follow the directions for use for them to be effective. I would say that anyone who says they don’t work, did not follow the instructions.

I have used these rocks for almost 2 months and I see no improvement on my lawn. I am also concerned because it doesn't seem like my dog is drinking enough of the rock water. I don't want to put my dogs life in jeopardy.

I bought these to try instead of my usual brand rocks. You get an awful lot in the box, enough for a dozen in three drinking bowls, two outside and one inside. The only problem is that because you have so many, as opposed to three big ones, they are more difficult to clean and the outer rocks in the bowls outside go green whereas the other make didn't. But they do work and if you need a lot of the rocks then I would recommend these. Very good value from this point of view.

We have 2 female dogs, one spaniel and a lab. The rocks have been used from date of purchase in April every day, it being the only water the dogs have. The lawn was newly re-turfed in April. Burn patches all over the lawn with new appearing daily. We have even re seeded some areas.The only thing we have found to work is putting a watering can of water on the pee location immediately after they have been to the toilet. Even then it’s hit or miss with patches still appearing.Don’t waste your money like we did. Unfortunately it doesn’t work.

I tried this product over a year and it hasnt helped. I followed the instructions, ensuring that the rocks marinated overnight in a jug with a tap, each night for 10-12 hours. We renewed our lawn and the patches came back again. I wish it had worked. I am now trying another make as I noticed a few comments on here saying that the other brand worked.

Was prepared to put up with the faffing around with jugs of water and 12 hour soaking time, just to save our lawn, but can safely say after a good 10 weeks that this has made no difference with our 2 greyhounds and Lurcher - the grass is still dying every time they pee on it. A waste of money unfortunately.

When I purchased Peterals I really did not think they could solve the dead grass problem and two weeks later still dead grass, because of health problems could not attend to it. Then after another two weeks after I had removed dead grass the green began to.come now 7weekd after purchasing we are backprou of our lawn. If you replace stones every 2 months as advised it will cost approximately £1 per week to have a lawn like you had before your best friend came to live with you!. Are'nt we lucky!!!!!
